背景:在一项多中心随机对照试验(HeRO试验)中,显示心率特征(HRC)评分与极低出生体重(VLBW)婴儿较低的败血症相关死亡率有关。本研究的目的是检验在诊断尿路感染(UTI)或脑膜炎时,无论是否伴有血流感染(BSI),HRC指数是否会升高。 方法:对2989名VLBW婴儿在出生3天后且在入组研究120天内的血液、尿液和脑脊液(CSF)培养数据进行了分析。使用配对符号秩检验,分析在培养阳性前12小时与前36小时的HRC指数。 结果:分别有10%、2%和24%的婴儿被诊断为尿路感染、脑膜炎和血流感染。与诊断前36小时相比,在诊断尿路感染和血流感染前12小时的平均每小时HRC指数显著更高(尿路感染为2.07对1.81;血流感染为2.62对2.25,两者均P<0.001)。对于脑膜炎,在诊断前12小时与前36小时的平均每小时HRC指数无显著差异(分别为2.18和2.08,P = 0.14)。在伴有血流感染的尿路感染病例中,在诊断前12小时与前36小时的平均每小时HRC指数差异显著(分别为2.28和1.86,P<0.001)。在伴有血流感染的脑膜炎病例中,在诊断前12小时与前36小时的平均每小时HRC指数差异显著(分别为2.46和2.03,P = 0.002)。 结论:在VLBW婴儿中,在诊断尿路感染和血流感染前12小时,HRC指数显著升高,但在诊断脑膜炎前无此现象。在伴有血流感染的尿路感染和脑膜炎病例中,在诊断前12小时HRC指数也显著升高。这些发现支持进一步研究HRC指数作为早期感染标志物的潜在用途。
BACKGROUND: Displaying heart rate characteristic (HRC) scores was associated with lower sepsis-associated mortality in very low birth weight (VLBW) infants in a multicenter randomized controlled trial (HeRO trial). The aim of this study was to test whether HRC indices rise before diagnosis of urinary tract infection (UTI) or meningitis, with and without concomitant BSI.METHODS: Blood, urine, and cerebrospinal fluid (CSF) culture data after 3 days of age and within 120 days of study enrollment were analyzed from 2989 VLBW infants. The HRC index was analyzed 12h prior to positive cultures compared to 36h prior, using paired signed-rank tests.RESULTS: UTI, meningitis, and BSI were diagnosed in 10%, 2%, and 24% of infants, respectively. The mean hourly HRC index was significantly higher 12h prior to diagnosis of UTI and BSI compared to 36h prior (UTI 2.07 versus 1.81; BSI 2.62 versus 2.25, both p
